The DiroDi Rover Standard is a fat-tyre electric bike built for real distance, not just short hops around town. This one’s the 500W version in Black, with a step-over frame suited to riders from about 160cm to 190cm. Hydraulic disc brakes, a 7-speed Shimano drivetrain and an integrated rear rack come standard, and it arrives 95% pre-assembled and ready to ride.
